A'NTIFRICTION-HULB.

Specification of Letters Patent.

Patented. July 11, 1916.

Application filed January 25, 1913. Serial No. 744,076.

To all whom it may concern.

Be it known that we, HARRY L. ALDER and HENRY E. GILFERT, citizens ofthe United States, residing at Stockton, in the county of San Joaquinand State of California, have invented new and useful-Improvements inAntifriction-Hubs,'of which the following is a specification.

Our invention, as disclosedherein, relatesbroadly to an improvedanti-friction hub, that is a hub wherein loss of energy due to frictionis reduced to the minimum.

An object of our invention is to provide bearings are disposed in sucha'manner 'as to be obviously excluded from dust or foreign materials ofany nature.

Another object of our invention lies .in the provision of a device ofthe above character wherein the engaging members are readily detachablefrom the device consequently facilitating the attachment of new partswhen desired.

A further object of our invention is to pro vide-an anti-friction hub,wherein the axle proper is relieved from friction generated-by therotation of thewhe'e'l to a great extent.

A still further object of our invention is to provide a device of thetype above setforth which consists of but a few simple parts whereby itmay be manufactured and placed upon the market at a minim'um cost.

With the above and other objects in view, our invention relatesto suchdetails of construction and in the arrangement and combination of partsas will be hereinafter fully described and specifically pointed out inthe I appended claim.

'eral views, and in which In describing our invention in detail,reference will be had to the accompanying drawings wherein likecharacters denote like or corresponding parts throughout the sev- Figure1, is a cross sectional view of our invention illustrated in connectionwith an ordinary form of axle, Fig. 2, is a vertical sectional view ofour device showing the axle in elevation, Fig. 3, is a sectional view ofan anti-friction bearing which is used.

In the accompanying drawings wherein is illustrated the preferred formof our invention, the numeral 10 designates an axle, of the usual form,in connection with. which our invention has been illustrated but it willbe appreciated that the latter may be employed in connection with axlesof different spirit thereof.

In reducing our invention topractice, we

other types without departing from the have provided, fixedly mountedupon the latter being substantially semi-circular in cross section. Wehave also provided, a

second sectional bearing sleeve 14:, which corresponds in shape, to thering 12 and is provided upon its inner periphery with a pair of spacedapart ball races 15, the latter registering with the races 13consequently providingan annular circular recess wherein bearing balls16 may operate. The sleeve 14, is,as is clearly shown, disposed within ahub 17 the latter consisting of a body fpprtion opened at each end, oneend however being closed through the medium of a circular plate 18. Bythe provision of this plate 18, it will be recognized that dust andother foreign material is prevented from settling in the wearing partsof the bean ings consequently more readily assuring the operativeness ofour invention. end of the body portion 17 is closed through The other.

the medium of a second plate 19, which plate has a central openingprovided therein'for the reception of the axle 10 as is clearly shown inFig. 2. e have now pro vided means for securing the plates 18 and 19.securely in engagement with. the body portion ofthe hub and at the sametime holding the sleeve 1% in rigid relation therewith. v l

With the above point in view, we have provided a series of transverselyextending rods 21 which are screw threaded near their extremitles as isshown, the screw threaded portion receiving nuts 22. The rods 21 alsoextend transversely through the sleeve 14 whereby as above set forth thesame is held in rigid relation with the hub and ailowed to rotate withthe same about the ring 12.

For purpose of assuring the constant oiling of the bearings and workingparts of the hub without constant attention, a quantity ofoil saturatedpacking material 23 is disposed between the plate 19 and the edges ofthe ring-12 and eeve 14. By the manipulation of the nuts 22, it will beappreciated that the packing material may be compressed so as to allowthe oil in the same to flow to the hearin in the device and c nsequently SIlfilClBIltlYflbPlCfit6 the same. ih platelQ is provided withenlargements lIltO the space between-the plate and the.

ring and bushing. These enlargements ens. gage the packing 23 andprevent Inovemen}:

of thepacking as the axle rotates. a It will be appreciatedfromtheioregoing disclosure that our-invention may be efiicientlyemployed upon mining c'arsof different types in View. of the fact thatgreat difficulty is incurred in providing means-for supporting theconstant ried therein.

Such changes as are permissible by the subjoined claim may be resortedto without departing from the spirit of our invention.

Having thus fully described our invention, what We claim as new anddesire to secure by Letters Patent is In a device of the characterdescribed a upon said' bushing rin "ms-bee a t a-plate fitting againstthe of said hub extending from the inner face of the plate mg and endsof said great weight carconnected with bushing" ring, a collar rotatablymounted g anti-friction means positioned between said h ub'fitting uponsaid collarand being provided at one ad with an inwardly extendingabutme flange engaging said collar and hav' 16S opposite end portionextendthe ends of said ring and collar, extending end and extending inspaced rela- -tijon to said collar and bushing to provide a packingpocket, said plate being provided ment with the central opening of saidbushhaving enlargements formed upon the inner face of said plate andextendin into the space between said plate and the collar and bushingring to provide securing means for packing plates therein, a closureplatefitting against the opposite end of said hub, and securing meansextending through said collar and said plates to hold the same in tightengagement with said hub.
